An out-of-memory error
There is no direct relationship between the size of a file in your computer and the amount of memory
needed in the printer to print the file. In fact, because of file compression and other complicating factors
it is often impossible to estimate how much memory will be needed. So it is possible that a print will fail
for lack of memory even though you may have successfully printed larger files in the past. In this case
you may need to consider adding more memory to your printer.

Color emulation modes
Your printer can emulate the color behavior of other devices: RGB devices such as monitors, and CMYK
devices such as presses and printers. See 
Select the color emulation mode on page 69.
If you have problems making your printer emulate another HP Designjet printer, see
Color matching
between different HP Designjets on page 157.
For a good emulation, the printer needs a specification of the colors these devices can reproduce. The
standard way of encapsulating such information is in...
